What counts as commercial door hardware?
When we say commercial door hardware, we mean everything on a business door that lets it open, close, latch, and lock. A commercial door gets used far more than a house door, and the hardware is built heavier to match. It is also more likely to fail in ways that leave a business unable to close up for the night.
Most calls we get in this category involve one of the parts below. Often the owner can't tell which one is the problem, and that's fine. Working that out is our job.
- Mortise lock bodies, the deep rectangular lock set into the edge of the door, common on older storefronts and office suites
- Cylindrical and tubular latch sets, the lever or knob style used on interior office doors, storerooms, and restrooms
- Strike plates and door frames, the part the latch actually catches on
- Deadbolts and auxiliary locks added to a door for extra security
- Exit devices and push bars, the hardware on doors that have to open from inside without a key
- Hinges, pivots, and door closers, which decide whether a door hangs square and shuts fully
Why won't my commercial door latch?
A commercial door that won't latch is the most common hardware complaint we hear. The door swings shut, but the bolt doesn't catch, and it drifts back open. It is easy to treat as a minor annoyance, and it usually isn't minor, because a door that doesn't latch also doesn't lock. The building is effectively open.
The cause is almost always one of a handful of things, and a technician can usually spot it quickly with the door in front of them:
- Door sag: worn hinges or loosened screws let the door drop slightly, so the latch no longer lines up with the strike
- A misaligned or damaged strike plate, often bent by a door that has been slammed or forced over the years
- A latch bolt that is worn, gummed up, or sticking inside the lock body
- A broken spring inside a lever set, so the handle droops and the latch doesn't retract or extend properly
- A door closer that is too weak, too strong, or set wrong, so the door arrives at the frame too slowly or too hard to engage
- Frame movement, where the building has shifted or the frame has loosened from the wall
Why won't my commercial door lock?
A door that latches but won't lock is a different problem, and it points to a different set of parts. The key may turn without moving the bolt. The key may not turn at all. The thumb turn on the inside may spin loose. Each of these tells us something before we touch a tool.
If the key spins freely, the connection between the cylinder and the lock body has usually failed, or the cylinder's tailpiece has broken. If the key turns hard or sticks, the cylinder is often worn or dirty, or the door is binding on the bolt because of alignment. If the bolt moves but doesn't reach into the frame, we're back to a strike or sag problem.
One caution: if a key has snapped in the lock, stop turning it and don't try to pull it out with pliers. That's a separate job, covered by our broken key extraction service, and forcing it tends to turn a simple extraction into a lock replacement. If you're locked out altogether rather than dealing with a failing lock, our business lockout service is the right place to start.

Call (213) 577-1366How do we fix commercial door hardware, step by step?
Every hardware call is a little different, but the order of work stays the same. We'd rather you know what to expect before a van pulls up.
- You call (213) 577-1366, any hour, and describe what the door is doing: won't latch, won't lock, sticks, or won't open from one side. Photos help if you can send them, but they aren't required.
- We ask a few practical questions: the type of door, whether it's an exterior or interior door, whether the building needs to be secured tonight, and whether anything was recently changed.
- A technician comes to the site. We don't dispatch your job to a third party, because we are one company with our own vans and our own storefront.
- We inspect the whole door, not just the lock: hinges, frame, strike, closer, latch, and cylinder. Treating only the symptom is how the same call comes back a month later.
- We explain what we found in plain terms and give you the options, repair or replace, before any work begins. You decide.
- We make the repair or install the new hardware, then test the door repeatedly from both sides, with the key and without, to make sure it latches and locks every time.
- If the building has to be secured and the permanent fix needs a part we don't have on the van, we explain the safest temporary arrangement and what the follow-up involves.
Should a mortise lock be repaired or replaced?
Mortise locks deserve their own discussion because they behave differently from ordinary locks. A mortise body sits inside a deep pocket cut into the door edge, and it holds the latch, the deadbolt, and often the trim connection in a single unit. They were built to last, and many older commercial doors still carry one that has been working for decades.
That durability is why we lean toward repair when repair makes sense. Internal springs, a worn cylinder, or a stuck bolt can often be dealt with without pulling the whole lock out of the door. Replacement of the cylinder alone is a lighter job than replacing the full lock body.
Replacement becomes the better path when the body is cracked, when internal parts are stripped, when parts for an older model are no longer available, or when the door needs hardware that meets a current requirement the old lock can't satisfy. Swapping a mortise lock for a different style can mean cutting or filling the door, so we'll tell you honestly if a like-for-like replacement is the cleaner route.
Doors that must open from the inside without a key, such as exit doors, bring their own considerations. If yours is one of them, a panic bar installation may be part of the conversation, and we'll raise it rather than hope nobody notices.

Call (213) 577-1366What affects the cost of commercial door repair in Willowbrook?
We don't quote numbers on a web page, because a number given without seeing the door is a guess, and guesses are how customers end up surprised by the invoice. What we can do is show you exactly what moves the price, so the quote you get later makes sense.
The main factors are these:
- The type of hardware. A standard cylindrical latch is a different job from a mortise lock or an exit device, in both parts and labor.
- Repair versus replacement. Adjusting a strike or re-hanging a sagging door is usually the more economical route when the lock itself is sound.
- Availability of parts. Common hardware is easy to source. Older or specialty mortise bodies can take more effort to match.
- The condition of the door and frame. If the real problem is a damaged frame or a warped door, the lock repair is only part of the fix.
- Door material and finish. Steel, aluminum storefront, and wood doors each need different handling.
- Whether you need keying changes, such as matching existing keys or setting up a master key system across several doors.
- Timing. A planned repair during business hours is a different job from an after-hours call where a building has to be secured right away.
Why call Wilshire Lock & Key for commercial door hardware?
We've been in business since 1987, and a lot of commercial hardware was already old when we started working on it. That history matters because commercial doors don't come in one flavor. A technician who has handled many generations of mortise locks, latches, and frames spots the problem faster and doesn't have to experiment on your door.
We run a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans, so the work isn't a phone number routed to whoever answers. You're dealing with one company, not a dispatcher passing the job along. David, the owner and lead technician, oversees the work.
A practical point on credentials: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for that number before they start work on your business. It's a fair question for anyone, including us.
If your needs go beyond one failing door, our wider commercial locksmith service covers the rest of the building, and our phone line is answered around the clock, year-round.
Commercial door hardware around Willowbrook's corridors
Willowbrook is an unincorporated part of Los Angeles County, about 18 miles from our Westwood storefront, and its ZIP codes, 90059, 90061, and 90222, cover a mix of commercial strips, medical facilities, and housing. The hardware problems we see tend to follow that mix.
Around the Martin Luther King Jr. medical campus district on 120th Street, medical office and clinic lock service is a real scenario. Clinics and offices usually have a mix of public entrances, staff-only doors, and storerooms, and each one wants different hardware. A front door that has to open easily for visitors and still lock firmly at night is a very different job from a supply room that must stay secured. When a latch fails in a setting like that, the repair needs to be tidy and quick to test, and sometimes it ties into access control, which is a conversation for our access control installation page.
Along the Wilmington Avenue corridor and El Segundo Boulevard, the typical call is a storefront door: a mortise lock that has worn out, a latch that drops out of alignment as the door sags, or a strike plate that has been bent by years of daily traffic. For those, we cover the details on our storefront lock repair page. The Imperial Highway corridor and the area around Rosa Parks Station add more foot traffic and more doors opening and closing all day, which is simply what wears hardware out.
The climate helps. This is a flat coastal plain with a morning marine layer and mild temperatures, and salt-air corrosion is not a significant factor this far inland. So the failures we diagnose here are usually from use: loose screws, tired springs, sagging hinges, and old parts that have reached the end of their service life. Older properties in the area often carry aging hardware, and multifamily buildings cluster near the transit and commercial corridors, so shared entry doors and mixed-use buildings come up as well.
If a door fails at night and the building can't be left unsecured, that falls under our emergency locksmith service, and we pick up the phone at any hour.

We answer around the clock, every day of the year.
Call (213) 577-1366What can you do before we arrive?
A few simple checks help us, and a couple of things are best left alone. None of this replaces a proper inspection, but it saves time on site.
- Note exactly what the door does: won't latch, won't lock, won't unlock, sticks, or only fails from one side.
- Check whether the problem happens with the door open as well. If the lock works fine open and fails closed, alignment is the likely cause.
- Look for a loose handle or lock body, which you can sometimes see or feel when you push on it.
- Don't oil the lock with heavy grease or force the key. Both tend to make a mechanical problem harder to diagnose.
- If the door can't be secured, keep it attended or move valuables out until a technician arrives.
- Have the key set, or any existing master keys, ready if the work involves re-keying.
Frequently asked questions
Why does my commercial door open back up after I close it?
The latch isn't catching. The usual causes are a door that has sagged out of line, a bent or misplaced strike plate, a worn latch bolt, or a door closer that's set wrong. Because a door that doesn't latch also doesn't lock, it's worth getting looked at the same day.
Can you repair a mortise lock, or does it always need replacing?
Many mortise locks can be repaired. A worn cylinder, a weak spring, or a sticking bolt can often be fixed without replacing the whole body. If the body is cracked, stripped, or can't be matched with available parts, replacement is the better route, and we'll explain which applies before we start.
Do you handle office door lock repair and warehouse door lock repair?
Yes. Office doors usually involve lever sets, deadbolts, and interior latches. Warehouse doors tend to be heavier, with hasps, exit devices, or rough-use hardware. We work on both, and the first step is the same: inspect the whole door, not only the lock.
Is a door that won't latch an emergency?
If it's an exterior door and you can't secure the building, yes, it's worth calling right away. Our line at (213) 577-1366 is answered 24 hours a day, 7 days a week. If it's an interior door and the building is secure, it can usually wait for a regular visit.
Can the problem be the door closer instead of the lock?
Often, yes. A closer that shuts the door too slowly or too softly won't push the latch into the strike. We check it during every hardware inspection, and if it needs work, our door closer repair page explains how that job goes.
How do you price commercial door repair without seeing it?
We don't give numbers over the phone without knowing what's on the door, because that would be a guess. We explain what affects the cost, inspect the door, and give you the options before any work begins. Repair is often the more economical route when the lock itself is still sound.
Can you match new hardware to my existing keys?
In many cases, yes, depending on the lock brand and type. If you're replacing a lock but want to keep your current key set, tell us when you call. If the original hardware is unusual, we confirm what's possible on site rather than promise it over the phone.
How do I know a locksmith is legitimate before they work on my business?
California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith for the number before work begins, and expect a clear explanation of the problem and your options. Be cautious of anyone who won't explain what they're doing or pressures you to replace everything.
